Phytoplankton variability in Lake Bourget: Phytoplankton dynamics and meteorology

This paper presents the phytoplankton succession during two successive years in Lake Bourget, a deep subalpine lake recovering from eutrophication. A drastic reduction of the watershed phosphorus loading in 1980 stopped lake eutrophication. At present, the lake has nearly reached constant winter (Ja...

Description
Summary:This paper presents the phytoplankton succession during two successive years in Lake Bourget, a deep subalpine lake recovering from eutrophication. A drastic reduction of the watershed phosphorus loading in 1980 stopped lake eutrophication. At present, the lake has nearly reached constant winter (January–February) nutrient concentrations. However, during the 2 years of the study, the phytoplankton data set shows a great interannual variability, which is analysed on the basis of the meteorological forcing variables.
